CVE-2025-30056: RunCommand Function RCE Vulnerability

CVE-2025-30056 Overview

CVE-2025-30056 is a critical command injection vulnerability affecting the RunCommand function. The function accepts arbitrary parameters that are passed directly to the shell for execution without proper validation or sanitization. This allows an attacker with adjacent network access to execute arbitrary code on the target system, potentially leading to complete system compromise.

Critical Impact

Attackers can execute arbitrary commands on the target system through the unsanitized RunCommand function, potentially achieving full system compromise with high impact on confidentiality, integrity, and availability.

Technical Details for CVE-2025-30056

Vulnerability Analysis

This vulnerability is classified as CWE-94 (Improper Control of Generation of Code, also known as Code Injection). The RunCommand function fails to properly validate or sanitize user-supplied input before passing it to the system shell for execution. This architectural flaw creates a direct pathway for attackers to inject and execute malicious commands within the context of the vulnerable application.

The vulnerability is exploitable from an adjacent network, meaning an attacker needs to be on the same network segment as the target system. However, the attack requires no user interaction and no special privileges, making exploitation straightforward once network adjacency is achieved. Successful exploitation results in complete compromise of the affected system, with cascading impacts possible on connected systems.

Root Cause

The root cause of CVE-2025-30056 lies in the improper handling of user input within the RunCommand function. The function directly passes user-supplied parameters to a shell interpreter without implementing input validation, sanitization, or parameterized command execution. This violates the fundamental security principle of never trusting user input and creates a classic command injection vector.

Attack Vector

The attack vector for this vulnerability involves adjacent network access. An attacker positioned on the same network segment can craft malicious input containing shell metacharacters or command separators (such as ;, |, &&, or backticks) to inject additional commands into the shell execution context.

The vulnerability manifests when the RunCommand function concatenates user input directly into a command string that is then executed by the shell. Without proper escaping or the use of safer execution mechanisms, the attacker's injected commands are executed with the same privileges as the vulnerable application.

Detection Methods for CVE-2025-30056

Indicators of Compromise

• Unusual process spawning from the affected application, particularly shell interpreters (/bin/sh, /bin/bash, cmd.exe)
• Unexpected network connections originating from the vulnerable service
• Log entries showing malformed or suspicious parameters in RunCommand function calls
• Evidence of reconnaissance commands (whoami, id, uname) in process logs

Detection Strategies

• Monitor application logs for anomalous input patterns containing shell metacharacters (;, |, &&, ||, backticks, $())
• Implement network-based intrusion detection rules for command injection payload patterns
• Deploy endpoint detection to identify unexpected child processes spawned by the vulnerable application
• Utilize SentinelOne's behavioral AI to detect post-exploitation activities indicative of command injection attacks

Monitoring Recommendations

• Enable verbose logging for the affected application to capture all RunCommand function invocations
• Implement real-time alerting for any command execution attempts containing known injection patterns
• Monitor for lateral movement activities from systems running the vulnerable software
• Establish baseline behavior for the application and alert on deviations

How to Mitigate CVE-2025-30056

Immediate Actions Required

• Restrict network access to systems running the vulnerable application to trusted hosts only
• Implement network segmentation to limit adjacent network exposure
• Deploy application-level firewalls or input filtering to block common command injection patterns
• Monitor vulnerable systems for signs of exploitation while awaiting a vendor patch

Patch Information

Specific patch information is not currently available in the vendor advisory. Organizations should monitor the CERT Polska advisory for updates regarding remediation guidance and vendor patches.

Workarounds

• Disable or restrict access to the RunCommand function if not operationally required
• Implement input validation at the network perimeter using web application firewalls or similar controls
• Deploy network access controls to limit which hosts can reach systems with the vulnerable function
• Consider isolating vulnerable systems to dedicated network segments with strict egress filtering

# Example network isolation using iptables
# Restrict incoming connections to specific trusted hosts
iptables -A INPUT -s 192.168.1.0/24 -p tcp --dport <app_port> -j ACCEPT
iptables -A INPUT -p tcp --dport <app_port> -j DROP
